This would be such a huge immersion enhancer, as I'm currently making a Rice Paddy in Enigmatica 6, and if these could be planted in water, and not be immeditaly destroyed by the water that would make the whole thing look so much prettier :)

If waterloggin would be too much effort, or impossible with seeds, maybe a new type of farmland?
1 Bucket of water surrounded by dirt = 8 puddlelands. Works exactly the same as farmland, but it doesnt dry out, ever.. and has connected textures of a 2 pixel deep water graphic. (2 deep cause, 16/8 = 2 ya know ? lol
